Fast, Reliable Sliding & Patio Doors Across Union Park
Sliding door replacement in Union Park usually runs $1,800 to $4,600 depending on the opening width and what we find once the old unit comes out. That’s the honest range for this market, not a teaser number that climbs after the contract gets signed. We’ve worked Union Park long enough to know that a 1972 CBS ranch on a canal lot behaves differently than a 1984 expanded ranch off Dean Road. Every job starts with the same question: what’s actually behind that aluminum frame, and will the Orange County Building Division accept what we’re putting back. Call (813) 320-9346 and we’ll come measure both the door and the opening before we quote anything.
We know the permit path here runs through Orange County, not a city hall, because Union Park is unincorporated. That changes what product documentation gets filed, which wind-load specs the reviewer checks, and how long the approval takes. If you’ve lived in Union Park twenty or thirty years, you already know how the county works. So do we.
Why TruePane Windows & Doors Is Union Park’s Preferred Sliding & Patio Doors Company
We’ve been replacing doors in Union Park for years now, and the same patterns keep showing up: original aluminum sliders with worn roller tracks, jalousie panels in converted Florida rooms, and sills rotted from inland humidity. Our Sliding & Patio Doors team measures twice before ordering anything, because a 5-foot rough opening in a 1974 CBS rancher is rarely square anymore. We quote manufacturer lines side by side on paper so you see exactly what you’re paying for.
Dale Kessler founded this company in 2008 with one rule that still governs every install: if the pane is not true, the job is not done. That means we don’t shim a bowed jamb and call it a day. We don’t skip flashing tape because the inspector might not look. And we register both manufacturer warranty layers in writing before the truck leaves your driveway. That’s The Keystone Standard, and it’s on every Union Park job we touch.
Our technicians are background-checked and uniformed. A live person answers the phone 24/7, which matters when you’ve got a slider that won’t latch and it’s July. We’re not the cheapest bid in Union Park, and we won’t pretend to be. We’re the company that stands behind the work, in writing, for 90 days with no paperwork fights.
Our Sliding & Patio Doors Services in Union Park
Patio Sliding Doors
Most Union Park homes built between the late 1960s and mid-1980s have original aluminum sliders that are now 40 to 55 years old. What we find when we pull them: bent jambs, worn roller tracks, failed seals, and no thermal break. The glass is single-pane in a lot of cases. We replace these with modern units that meet Florida Building Code wind-load requirements for inland Orange County, and we register the manufacturer warranty for both the glass and the frame on paper.
If your patio slider binds when it’s humid or jumps the track when the grandkids lean on it, that’s not a lubrication problem. That’s a frame problem. We’ll tell you straight what’s fixable and what needs full replacement, then quote both options with actual numbers.

Heavy-Duty Sliding Doors
Heavy-duty sliders make sense in Union Park for a few reasons. First, the older CBS construction has solid masonry walls that hold a heavier door without issue. Second, multi-panel sliders with impact-rated glass handle Florida’s humidity swings better than lightweight frames that flex. Third, a heavy-duty track holds up to daily use from a big family without sagging over a 6-foot or 8-foot span.
When we replace an original aluminum slider with a heavy-duty unit in Union Park, we check the header and lintel before anything goes back in. On a ranch just off Dean Road, we pulled a rusted 5-foot aluminum slider from a converted Florida room and found the lintel had settled a half-inch with no flashing tape behind the nailing fin. We reframed the opening to a 6-foot rough, installed a ViewLux vinyl slider with low-E glass and argon fill, flashed the perimeter, sealed the jamb pockets, and had it inspected. That’s the difference between a door swap and a door done right.

Pocket & Barn Doors
Older Union Park ranches love a good pocket door. They save floor space in tight hallways and make sense for converting a formal dining room into a den or office. The catch: opening a load-bearing interior wall for a wide pocket door means pulling a permit through the Orange County Building Division, and that can trigger structural review on a 50-year-old CBS home.
We handle the whole path: check the wall, size the header properly, pull the permit, set the pocket frame square, and install a door that slides clean on the first try. Barn doors are a good alternative when you don’t want to open the wall at all. We install both, with the same warranty registration and the same 90-Day Done Right Promise.

Screen Door Installation
Union Park’s inland heat island means screen doors take real weather. Rain drives in from the east in summer, pollen covers everything in spring, and humidity never quits. We install sliding screen doors sized to the existing track, and we’ll tell you honestly whether your old track is worth saving. If the rollers are shot and the track is bent, replacing just the screen panel buys you maybe two years. We’d rather give you a number that lasts.

Trusted Brands We Service in Union Park
We’re an authorized installer for more than a dozen manufacturer lines, which means we can quote a PGT impact slider next to a Simonton vinyl unit and show you the difference on paper. Not a brochure glow-up. Actual specs, actual warranty durations, actual prices. For Union Park customers who want Florida-focused products, PGT and CGI both make wind-rated sliders that hold up to Orange County’s FBC requirements. We also service and replace hardware on Ply Gem and Simonton doors already installed in the area. Our warehouse keeps common rollers, tracks, and latch sets stocked, so a hardware-only repair in Union Park doesn’t wait on a freight truck from out of state.
Common Sliding & Patio Doors Problems We See in Union Park Homes
After years of working this specific market, here’s what keeps coming up in Union Park:
- Worn roller tracks on original aluminum sliders. These 1960s and 70s units have nylon rollers that disintegrate over time. The panel then rides on the metal track itself, which bores grooves into the aluminum and eventually binds. By that point, the jamb is usually bent too, and the panel won’t latch. It’s a security failure as much as an energy failure.
- Fogged insulated glass with zero argon fill. Older double-pane units lose their seal after 15 to 20 years in Orlando’s inland humidity. The space between the panes gets moisture, the low-E coating oxidizes, and the insulating gas is long gone. Replacement glass can fix this, but if the frame itself is aluminum and failing, you’re patching a tire that’s not holding air.
- Rotted wood sills on patio doors. Interior humidity from Orlando’s inland heat island keeps level in older homes without proper sill flashing or jamb gaskets. Water wicks into the wood frame at the threshold, swells, then rots. On ground-floor CBS ranchers with slab foundations, that rot often extends under the interior plate before it’s visible.
- Jalousie panels in converted Florida rooms. Union Park has a lot of rear additions built in the 70s and 80s that used jalousie glass. Those panels leak conditioned air year-round, and they fail Orange County’s FBC energy review on replacement permits. A simple patio door swap on a converted Florida room can trigger a full permitted replacement with approved product specs because the surrounding glazing is non-compliant.

FAQs - Sliding & Patio Doors in Union Park
Orange County requires FBC product approval documentation showing your new door meets current wind-load requirements for inland Orange County, even though Union Park isn’t in the highest coastal wind zone. The reviewer will check the door’s design pressure rating against the building’s exposure category, and they’ll want to see the opening inspected after rough-in. We file all of that with the permit. You don’t have to guess what the county wants. Call (813) 320-9346 and we’ll walk you through the exact paperwork path for your street.
Because the surrounding walls and adjacent fenestration are often original single-pane aluminum or jalousie glass that doesn’t meet current Florida Building Code energy minimums. Orange County’s review treats the door as part of the whole assembly, not an isolated swap. If the rest of the wall fails code, you can’t just drop in new glass and call it done. We’ll explain what has to happen before you spend money on a fix that won’t pass.
In most 1960s and 70s CBS ranches, we find exactly what the platform suggests: the interior wall framing is often undersized for the new span, there may be electrical runs notched through studs, and the wall base plate may be moisture-damaged from slab wicking. We inspect first, quote the structural work as a written allowance, and if we find something the original builder buried in there, you approve the number before we touch it. No surprise line items on the bill.
Yes, but the jalousie panels around the door will likely trigger the Orange County energy review. Once that happens, the county requires the entire assembly to meet current FBC standards, which means the jalousie glass gets replaced with approved glazing products. We’ve done this in Union Park: it turns a simple door job into a full room enclosure upgrade, but the result is a room you can actually use in August. We quote the full scope honestly before the first panel comes out.
We take photos and show you exactly what we found. Then we price the fix as a line item and get your written approval before any work changes. The contract already includes allowances for common framing issues in Union Park homes, so a rotted sill or a settled lintel doesn’t become a standoff. This is what Dale Kessler built TruePane on: if the wall’s not right, the door can’t be right. We fix the wall, then we set the door. Call (813) 320-9346 to schedule a free estimate.
